Companies like Oracle are using Tallyfy, and you can get lifetime of the Pro level product for just $39. One time payment.
You can run an entire business empire with this.

There’s 5 days left to get this lifetime (Appsumo) deal (Thursday 2/1/18). I was late to the party but glad I found it now. These often are once only deals so make sure you grab it today to avoid disappointment.

(if you don’t like or use you have a 60 day no questions refund period).
